Application iled March 23, 3.919. i- 'Serial No. 551,049.

To all ulmn.' it muy concern.'

Be it known thatI, Lao F. ADT, of Albany, in the county of Albany and State of N ew York, have invented certain new and useful Improvements in Eyeglass-lountings; and I do hereby declare the following.l to be a full, clear, and exact description or the saine, reference being had to the 'accoinpanying drawings, forminga part of this specification, and to the reference-numerals marked thereon.

The present invention relates to eye inountings particularly of the finger piece type in' which the guards' areinoved,

toward the nose under the action of individ ual springs, and an object of the invention is to provide a construction in which tinl springs are protected and hidden from viev.

` from the front of the mounting.

Another object is to provide a construe! tion in which the springs Will be retained in place and under tension when the guards are removed from the mounting for repair or other purposes and in which the springs may similarly be removed without disturbing the other parts.

Still'another object is to provide means for adjusting of the tension of the springsl so thatthe pressure of the guards on the nose may be varied.

To these and other ends the invention consists in certain improvements and cornbinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims atv the end of the specification. 1

ln the drawings Figurel l is a from view of n mounting constructed in accordance with the present improvements, one of the guards and its spring being removed: Fig. 2 is a plan view of the mounting with .one of the guards removed and its spring held to the mounting under tension: Fig. 3

is a bottom' View of the mounting with one of the guards` removed: Fig. liris a transverse section on the line o o, Fig. 2.

and Fig. 5 is a rear View of a portion of" the mounting 1n proximity to one of the.

`The guards swing on the support preferably on the upper side thereof and each preferably embodies a nose engaging meinber having an upper' pad 5 and alower pad G supported at the rear end of a lever 7. The lever extends transversely of the plane or the lenses held byv the support, and has at its forward end a linger piece or operating portion 8 which is bent downwardly at 9 in front of the support. ln order that the guards may have swinging or pivotal action the Shanks or connecting portions 4 of the support carry screws which project above wandbelow' the support, the upper end of each being provided with a head 10 for cooperation with the upper surface of a guard lever, and with a bearing 11 engaged by a laterally opening recess or bearing in a guard lever which also turns in engagement with the upper surface of the connecting portion 4. A shoulder 12 is preferably provided on the screw lto engage the upper surface of the connecting portion and prevent lthe clamping of the guard by the screw.

' The guards in this instance are moved toward the nose under the action of coiled springs 13. These springs are preferably arranged Within pockets 14 formed on the under side of the support about the depending portions 15 of the screws, said depending portions being surrounded by the coils of the spring.' Each spring may have an arm 16 extending into connection with its 'guard and for this purpose the t'ront Wall or the'pocket 14: may be provided with a horizontal -slot 17 through which the arm 16 vextends into engagement with the depending portion or finger piece 8 of the guard, the latter serving to hide the slot. 'Toltheend' that the-spring arm may enter the .slot 17 each pocket may be provided with a vertical slot 18 connecting with the horizontal slot 17 and opening at the bot! ton'rf the pocket.' Each spring arm 1 6 when disengaged from its guard, may be engaged' "with a shoulder 19 formed by n otchinge` pocket at the inner end of its slot 17. 'f he purpose of this arrangement is to retain the spring on the support under tension when its guard is removed fromA the support.

Owing tothe fact that the springs of eyeglass mountings of this type must,neces eerily be small in order to provide an inconspicuous structure, great diiiioulty has been experienced in maintaining proper tenyvision has been made in this invention for' varying the tension of the guard positioning springs. Preferably .this result is effected by providing a plurality of shouldersv 20 on the support for engagement' by the end 21 of the spring, these shoulders being formed in this instance by notching the rear Wall of the pocket thereby rendering them invisible from the front of the mounting.

To remove the mounting from the nose or to place it thereon, it is merely necessary to press the iin-ger pieces 8 toward each other, thus separating the nose bearing portions vin rear of the support. When the finger pieces are released, the nose bearing-portions move toward each other under the action of the springs 13. The guard may be detached by disengaging the spring arm 16 from the linger pieces S being held inl engagement with the bearing 11 by the action of the spring. T he springs may now be removed or held tothe support by engaging the arms 16 With the shoulders 19. To vary the tension of the springs the arms 21 are engaged With the proper shoulders 20.

, An eyeglass mounting constructed in accordance with this invention has its 'springs so arranged that they are invisible :trom the front of the mounting and, in the present embodiment, act to retain the guards on the mounting by continuously urging them into their bearings; but are detachable from the mounting,.provision being made by which' they may be retained upon the` mounting when the guards are removed and it Will be further noted that in detacliing the spring over the free ends otlieir centering pro,-`

jections as'constituted by the' screws or pivots, neither the latter nor the guard are necessarily disturbed in their positions. Con

versely, the guard alone or both the guard and the pivot may be removed Without detacliing the spring or greatly disturbing it..

beyond slightly reducing its tension which latter is still sufficient to hold it in place. The tension of the spring may be adjusted to vary the pressure of the guards upon the nose.
